Use of the iLogic Autodesk Inventor tool in the process of designing self-propelled drilling rigs

In the article, a practical example of using the Autodesk Inventor Professional iLogic tool for designing self-propelled drilling rigs has been presented. Self-propelled drilling rigs are advanced mining machines with a complex structure. At the design stage, most of the structural changes affect the stability, manoeuvrability and coverage area of the machine. Working on detailed machine models is timeconsuming and unnecessary in the initial phase of the project. Therefore, a parametric 3D model of a two-boom drilling rig has been developed. It enables a quick analysis of selected machine properties depending on a number of significant parameters. The most important dimensions, masses and centres of gravity of each subassembly are entered by transparent editing windows. Next, model tests are carried out taking into account the pass through a face end of a given width as well as the coverage area of a face with specific dimensions. At each stage of model tests, the location of the machine's centre of gravity against the stability triangle background is analysed. In addition, the model allows entering the longitudinal and transverse angles of inclination of the working as well as determining the distance of the centre of gravity from the tipping edge. The model is a practical tool that makes it possible to easily determine the inner and outer turning radius as well as the working area of the machine while constantly controlling its stability. Due to the use of simplified geometry of subassemblies, the changes in parameters result in an instantaneous change of the model and allow a quick analysis of their impact.
